TRUSS.

SPECIFICATION forming part of Letters Patent No. 339,333, dated April 6,1886.

Application filed January 29, 1886. Serial No. 190,145.

To all whom it may concern.-

Be it known that I, ADoLPn Sonnonns, a subject of the King of Prussia,and a resident of Rendsburg, in the Kingdom of Prussia, Germany, haveinvented a new and useful Improvement in Trusses for Buptures or Hernia,of which the following is a specification, reference being had to theaccompanying drawings.

The kind of truss to which this invention relates is composed of abelt-spring reaching from the back round one side of the body to thepart affected, and having attached to its back end a pad resting againstthe back of the person, while the front end carries the pressurepad thatis intended to act upon the rupture or affected part in front of thebody. The truss, if single, is kept in place by a suitable strap or bandconnecting the ends of the spring; if double, is kept in place by astrap connecting two such springs, each having a front pad.

The invention consists in the novel combination of an adj ustablepad-spring with a balland-sockct connection between the pad and thefront end of the belt-spring, as hereinafter described and claimed.

Figure l of the drawings is a plan of a single truss constructedaccording to my invention, the front pad and its connections being insection. Fig. 2 is aview corresponding with Fig. 1 of the front pad andpart of the belt-spring and their connections, but showing the paddifferently adjusted. Fig. 3 is a front view of the front pad and partof the belt-spring. Fig. 4 is a perspective View of a double truss,showing its application to the trunk of a human body.

Similar letters of reference indicate corresponding parts in the severalfigures.

D designates the front pad, constructed with a socket, s, fitted to turnloosely on the ballshaped head 0' of a bolt, 0, fastened to the end of ametal bar or arm, B, attached to the front end of the belt-spring A.

Between arm B and upper recessed part of pad Dis placed the pad-springf, that turns on bolt 0. The free end of this springf can, by

the truss.

(No modeLl turning the same on bolt 0, be brought to act on any part ofa circle of the outer side of pad D, so that at the corresponding partof the circle of its face the pad is pressed inward against the body ofthe person wearing Thus, while the truss is being applied, by merelyturning spring f the pad D can be brought to exert a pressure from rightor left, from top or bottom toward the opening of the rupture. Theposition of the pad can thus instantly be altered to suit the 0011-venience of the person wearing the truss. This will be understood withreference to Figs. 1 and 20f the drawings. In Fig. 2 thepressure of thepad is represented as exerted from the right, while in Fig. 1 thispressure is repi resented as exerted from the left toward the body ofthe person wearing the truss. p is a set-screw that may be applied tocounteract the pressure of spring f in some positions of the padforinstance, as shown in Fig. 1. Several such set-screws may be applied atdifferent parts of arm B. m is a nut by means of" which bolt 0 isattached or fastened to arm B. This nut may be used as attachmentfor thebelt or strap for keeping the truss in place.

K designates the back-pad connected by a ball-and-soeket joint, 6, witha bolt or stud, t, which is secured to a plate or bar, K, secured on therear end of the belt-spring. By this ball-and-soeket connection with thebelt-sp ring the back-pad is enabled to adjust itself to the back of thewearer.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination, with the front pad and the belt-spring, and theball-and-soeket connection r s between the said pad and spring, of thepad-spring attached to the bolt or stud c of said connection, andcapable of turning thereon to apply its pressure to various parts of thepad, substantially as and for the purpose herein described.
